dotnet-websharper/mvu

This system is the WebSharper.Mvu framework, which implements an Elm-inspired Model-View-Update architecture for building client-side web applications. It provides core capabilities including state management with synchronous and asynchronous commands, multi-page routing with CSS transitions, and integration with Redux DevTools for time-travel debugging. The codebase also includes a TodoMvc sample application and a test suite to demonstrate these features within an ASP.NET Core host.

A new paket template file (WebSharper.Mvu.paket.template) has been added to the nuget directory, defining the package metadata and dependencies for the WebSharper.Mvu library, specifically targeting netstandard2.0 with locked versions of WebSharper and WebSharper.UI.

This change introduces the WebSharper.Mvu library, an Elm-inspired Model-View-Update architecture for WebSharper applications, along with a complete TodoMvc sample implementation. The release includes core framework features such as time-travel debugging via RemoteDev integration, automatic local storage persistence, HTML templating support, client-side paging with CSS transitions, and URL routing. The project structure has been split into the main library, the TodoMvc sample, and a test project, utilizing FAKE and Paket for build automation and dependency management.

The WebSharper.Mvu library is introduced, providing a Model-View-Update (MVU) architecture for building web applications. It includes an \App\ module with \Create\ and \CreateSimple\ entry points, and an \Action\ type that supports synchronous and asynchronous commands (\Command\, \CommandAsync\) as well as combined actions. The framework adds a \Page\ and \Pager\ system for handling multi-page applications with CSS transition support and DOM optimization. Additionally, it integrates with Redux DevTools for time-travel debugging and state inspection, and provides a \WithRouting\ macro to bind URL hash routing to the application model.

The TodoMvc demo application now supports time-travel debugging via Redux DevTools. The runtime integration handles Redux DevTools actions such as JUMP\_TO\_STATE, JUMP\_TO\_ACTION, IMPORT\_STATE, RESET, ROLLBACK, and COMMIT, allowing users to inspect and revert application state changes directly in the browser's developer tools.

The TodoMvc application now uses locally hosted CSS files (base.css, index.css, rendering.css) instead of external CDN links, ensuring consistent styling without external dependencies. The HTML structure has been updated to reflect internal refactoring: the todo list template is now named 'Entry' instead of 'TODO', the edit trigger action is 'StartEdit' instead of 'ToggleEdit', and the editing input variable is 'EditingTask' instead of 'Task'. Additionally, the footer now dynamically displays the count of remaining items using the '${ItemsLeft}' placeholder.

The TodoMvc sample application has been reorganized to support URL routing (All, Active, Completed endpoints) and a component-based structure, splitting logic into Entry and TodoList modules. The build process now uses esbuild for bundling, and the ASP.NET Core startup configuration has been updated to use IWebHostEnvironment.

WebSharper.Mvu.TodoMvc · high confidence

Add test project entry page with CSS transitions; Added WebSharper.Mvu.Tests test project with Mvu demo and ASP.NET Core host; Added test assets for WebSharper.Mvu.Tests.

The WebSharper.Mvu.Tests and WebSharper.Mvu.TodoMvc projects have been upgraded to target .NET 8 and now use esbuild (v0.19.9) for frontend bundling instead of the previous tooling. This change introduces new package.json and package-lock.json files to manage Node.js dependencies, including esbuild and Redux DevTools packages, and updates the .fsproj files to invoke esbuild via npm scripts during the build process.
